Urinary Tract Infection Practice Questions with Answers and NCLEX® Review

The urinary system consists of the kidneys, ureters, bladder, and urethra. Most infections affect the lower urinary system. However, bacteria can enter the urinary tract causing a urinary tract infection (UTI) which can then progress to a kidney infection known as pyelonephritis.

    Introduction to Urinary Tract Infections

    Urinary Tract Infections (UTIs) of the lower urinary system (bladder) usually affect women more often than men (related to the length of the urethra). UTIs can be caused by bacteria, fungi, or other organisms such as chlamydia and mycoplasma. The hallmark symptom is pain or burning with urination.

    UTIs can be treated with prescribed antibiotics and increased fluids unless contraindicated. But an untreated UTI can progress and become pyelonephritis.

    Pyelonephritis is an infection when bacteria travel from the bladder to the kidneys. This infection can be acute or chronic and can involve one or both kidneys. Clients with an obstruction in their urinary tract (such as a kidney stone) are at risk for developing pyelonephritis.

    UTI Pathophysiology

    Most UTIs are caused by Escherichia coli (E. coli), a bacteria found in the intestinal tract. This bacteria can be transferred when cleaning after a bowel movement or from sexual intercourse. The bacteria leads to an infection that causes inflammation and discomfort.

    Other causes include:

    • Urinary retention
    • Benign prostatic hyperplasia (BPH)
    • Kidney stones
    • Foley catheters

    Signs and Symptoms:

    • Fever
    • Burning during urination (Dysuria)
    • Increased urinary frequency

    UTI Nursing Assessments and Interventions

    When a client presents with signs and symptoms of an infection, the nurse will obtain the appropriate prescribed specimens and cultures. Antibiotics should never be the first course of action before cultures. Interventions include:

    Administer antibiotics as prescribed.

    Encourage the client to practice proper hygiene and urinate frequently to flush out bacteria. They should also drink plenty of fluids, especially water.

    Educate clients on multiple points, such as

    • avoid using feminine hygiene products that contain dyes, fragrances, or other chemicals (such as bubble baths). 
    • female clients should wipe from front to bad to avoid bacteria
    • always urinate after intercourse
    • wear cotton underwear

    Pyelonephritis Pathophysiology

    Pyelonephritis is a more serious infection that affects the kidneys. Most often acute cases result from an ascending route of infection. A previous UTI that is unresolved, poor hygiene, age, instrumentation (such as catheters) or other underlying conditions. In a kidney infection there may be costovertebral tenderness. Other signs and symptoms include:

    • Dull flank pain
    • Fever
    • Chills (shivering)
    • Chronic pain or discomfort in the lower back or side (this may be felt as a dull ache or sharp pain)
    • Nausea and vomiting

    Pyelonephritis Nursing Assessments and Interventions

    Assess the client’s fluid intake and urine output 

    Monitor the client’s temperature about every four hours and signs of infection.

    Administer antibiotics as prescribed. 

    Provide pain relief with acetaminophen or ibuprofen if necessary. (If fever occurs with infection, acetaminophen or ibuprofen should not be used before the underlying condition is diagnosed and treatment begins).

    UTI Medications

    Sulfonamides and fluoroquinolones are medications that are typically used for urinary tract infections. These medications can stop the bacteria and prevent the infection from spreading.

    Sulfonamides

    Sulfonamides are antibiotics that can be used to treat bacterial infections. They work by blocking the growth of bacteria and killing them.

    Memory Trick

    • Sunburn (client needs to wear sunblock and avoid the sun)
    • Urine crystals and specific gravity
    • Love water (2-3L per day)
    • Folic acid (take daily)

    Mechanism of Action: Prevents the synthesis of folic acid. (binding and inhibiting the enzyme)

    Fluoroquinolones

    Fluoroquinolones are a class of antibiotics that can be used to treat a variety of bacterial infections. They contain a fluorine atom attached to their quinolone ring, which is how they received their drug classification.

    Mechanism of Action: They inhibit DNA gyrase, an enzyme that helps DNA unwind when it’s being copied. This inhibition results in cell death.

    Phenazopyridine

    Phenazopyridine Is a medication used to relieve symptoms caused by urinary tract infections. It is not an antibiotic and does not treat the cause of UTIs. Instead, it’s a dye that soothes the urinary tract lining and offers some pain relief. 

    Clients should be aware that it will cause the urine to become an orangish red and will stain clothing.

    During my exam, I could literally see and hear him going over different areas as I was answering my questions.

    This past Friday I retook my Maternity Hesi and this time, I decided for my last week of Holiday break to just watch all of his OB videos. I am proud to say that with Mike’s help I received a score of 928 on my Maternity Hesi!

    Nursing Interventions for UTI Conclusion

    Bacteria exposure can result in infections in the urinary tract, also known as UTIs. They most frequently cause burning or pain when urinating.  UTIs are typically treatable with medications, but occasionally they worsen and result in pyelonephritis, a kidney infection.

    Pyelonephritis is brought on by bacteria that enter the kidneys from the bladder. One or both kidneys may be impacted by this infection, which can be acute or chronic in nature.

    UTI medications include sulfonamides,and fluoroquinolones. They function by reducing bacteria in the urinary tract and halting the spread of the infection.
